Can 202 stainless steel magnets be sucked

304 or more) and so on, the magnet is not sucked, and if it is sucked, it must be fake.

202 stainless steel, the magnet is suctionable.

202 is made of austenitic material, but the element containing Fe is inside, so the magnetic permeability is not high, and it is difficult to absorb.

Stainless steel 202 is austenitic stainless steel and should not be attracted by magnets.

Any stainless steel has the largest iron content, so it can be absorbed.

Does a magnet attract stainless steelCan stainless steel be attracted by magnets.

If it is an austenitic stainless steel, it cannot be attracted by magnets, because this stainless steel contains a lot of chromium and nickel, which is not magnetic, so it cannot be attracted by magnets. If it is tempered martensitic stainless steel, it can be attracted by magnets, because this stainless steel needs to be heat treated during the production process, so that the stainless steel can be hardened, and during the treatment, the internal structure will be transformed, so that the stainless steel has magnetic conductivity, so it can be attracted by the magnet.

The selection has the word 304.

According to the regulations, all qualified products produced by regular brands need to be printed with the logo of 304 before leaving the factory, so when choosing stainless steel products, it is necessary to choose the logo printed with the words 304, so that stainless steel can meet the standard. If you buy a product that is not printed with stainless steel, it is likely to be a product of substandard quality.

302 stainless steel belongs to the American standard austenitic stainless steel, the implementation standard: ASTM A276 A276M-17

The corrosion resistance of 302 stainless steel is the same as that of 304, and the strength is better due to the relatively high carbon content, and it is used as a decorative part for construction.

The chemical composition of 302 stainless steel is shown in the following figure:

Micromagnetic. 302 stainless steel has a long history, stainless steel has good plasticity, toughness and cold workability in the solid solution state, good corrosion resistance in oxidizing acid, water, atmosphere and other media, and has high strength but poor elongation than 301 after cold working. However, in the sensitized state or after welding, it has a tendency to intergranular corrosion, so it is not suitable for welding structural materials.

It has good corrosion resistance for strong oxidizing acids, and has certain corrosion resistance for alkaline solutions and most organic acids. Its corrosion resistance is worse than that of stainless steel containing titanium and niobium and low-carbon 18-8 type.

No. "Stainless steel" is just a general name, the standard name is "acid and alkali resistant steel", stainless steel is a steel product made of chromium, nickel and other metal elements on the basis of ordinary steel, the higher the content of nickel, molybdenum, titanium and other metal elements, the better the quality of stainless steel. The traditional identification method is to use magnet suction, and the smaller the magnetism, the better the quality.

Only chromium contains chrome stainless steel, chromium nickel stainless steel is not attracted by magnets, used in industrial and chemical fields, general household appliances such as microwave ovens, rice cookers, electric water heaters, electric kettles are made of chromium stainless steel, can be attracted by magnets.

Real 302 stainless steel is magnet-free.

Pro, a strong magnet can absorb 304 stainless steel 1, if it is authentic 304 stainless steel, although it also has iron elements in it, but it is relatively small, and it cannot be attracted with magnets; However, if it is a product of poor quality, there will be more iron elements, and it can be easily attracted with magnets. Because this kind of stainless steel has poor corrosion resistance, it is also a way to distinguish between the best and the worst by using a magnet to suck 304 stainless steel. 2. Many products in life are made of 304 stainless steel, although there is a certain magnetism, but it shows weak magnetism.

Some products are magnetic, such as 316 stainless steel, which has more iron elements, so it will be magnetic. <>
